PANA — The 25-year-old man who was killed by an Illinois State Police SWAT team Tuesday pointed his handgun at his own head during the standoff, Christian County Sheriff Bruce Kettelkamp said.

“I believe he was under the influence of some type of narcotic,” Kettelkamp said. “He pointed the gun at his head several times and said he was going to take his own life. … We tried to talk him down (from the roof of the house). He just wouldn't come down.”

The incident occurred about 7 miles west of Pana in the vicinity of county roads 1498 East and 350 North about 3:15 a.m. Tuesday.

Josh A. Edwards was pronounced dead at the scene after he allegedly shot at members of the SWAT team and troopers returned fire.

Three other people were in the house when the incident began. All were arrested on charges including possession of a meth precursor, possession of drug paraphernalia and no valid Firearm Owner's Identification card, Kettelkamp said.

The three people arrested are: Stacy N. Reed, 29, of the 600 block of South Spruce Street in Nokomis; Courtney D. Herbison, 24, of Dickson, Tennessee; and Jason C. Beck, 37, of the 1400 block of 350 North Road, the location of the standoff.

Beck is Edwards' half brother.

Kettelkamp said Edwards came from Tennessee, but the sheriff didn't know how long he had been living at the house on 350 North Road. The sheriff's office was aware of suspicious activity at the house.

“We'd been seeing a lot of traffic going in and out of that residence. We had information that they were cooking meth at that location. We had not gathered enough information for a search warrant, but we were getting close,” Kettelkamp said.

Information from Tennessee authorities indicates that Edwards was convicted in Dickson County in 2007 for possession of less than half an once of marijuana. He was also convicted in 2008 in Hickman County, Tennessee, of reckless endangerment involving a deadly weapon and possession of marijuana.

Hickman and Dickson counties are west of Nashville.

Christian County deputies were initially sent to the house Tuesday to check a report of a man who might be armed and dangerous. While at the house, they discovered what appeared to be drug paraphernalia.

The deputies called the Central Illinois Enforcement Group for help. Two members of the group, one of whom is a Pana police officer, responded. When they arrived, Edwards allegedly shot the Pana police officer in the arm. The other officers returned fire, and Edwards fled to the roof of the home.

The Pana officer's injuries were not life-threatening.

Edwards was on the roof a few hours, during which time Kettelkamp tried to convince him to surrender.
